Lin Mu listened to their conversations until they stopped and returned to their tasks at hand.
He first observed the hall they were in and noticed its peculiarities, mainly the lack of formations and use of candles for lighting.
'So this is how they've reduced their traces as much as possible… They're using candles to prevent any fine fluctuations from leaving and are also containing their Qi. But this also means they cannot detect me as well.' Lin Mu grasped.
This worked in his favor, as it meant that he had a better chance at scanning everything in the room. Thus, he became bolder and decided to peek in directly with his eyes.
Of course, for this he moved to the roof first and then peeked down, with only his eyes coming out of the roof.
